                The coordinates of the vertices of  CDE are C(1, 4), D(3, 6), and E(7, 4). If the triangle is reflected over the line y = 3, what are the coordinates of the image of D?

    This one is fairly easy. The x-coordinates do not change, since we are rotating around a horizontal axis.
For the y-coordinates, just figure the distance above or below y=3, and change them to the same distance below or above.
(1,4) is 1 unit above y=3. Make it one unit below: (1,2)
similarly,
(3,6) -> (3,3-(6-3)) = (3,0)
(7,4) -> (7,3-(4-3)) = (7,2)

    It is not 3,-6 it is actually 3,0
the answers are as follows
1 -3,-1
2 3,0
3. the image and the preimage have different orientations
4. x=2
5. -5,7
hope this helps anyone :)
